I load because I can. My parents were born in Poland under communism and though we have all three grown up as studied, thoughtful, educated people, I am the one that has comparatively huge financial resources to share. I simply owe to others that which is not my wealth, but rather my good fortune.
I work in the education field, but not directly in the classroom. There are teachers of children, there are principals who organize and support a whole school of teachers, and there are superintendents who give help and information to schools. My work is in research, helping these educators, mostly principals and superintendents, to make decisions with information about how students learn, and what types of programs work well for as many as 100,000 students at a time.
